Researchers find original USPS analysis on electric mail trucks “significantly flawed”

College of Michigan (U-M) researchers declare “considerably flawed” evaluation led the USA Postal Service (USPS) to downplay the environmental advantages of electrical mail vehicles.

The Postal Service has used its evaluation to justify not making its whole fleet of next-generation mail vehicles electrical, which has drawn criticism from the White Home, Congress, and environmental teams. U-M claims its researchers performed a extra rigorous research that also confirmed a a lot bigger emissions discount than the unique evaluation.

“U-M researchers performed a cradle-to-grave greenhouse-gas emissions evaluation—often called a life-cycle evaluation, or LCA—of the 2 situations and reached some vastly completely different conclusions than the Postal Service did,” the college stated in a press launch. The LCA has a broader scope than the unique USPS research, which solely thought of emissions from precise use of the autos.

The talk over electrifying the USPS mail truck fleet began greater than 18 months in the past, with the shock announcement that solely 10% of the USPS next-generation supply vehicles could be electrical. That led environmental teams and a coalition of states to sue the USPS.

The USPS gave into strain this summer season, and now plans for 50% of its preliminary procurement of the next-generation autos to be electrical, and when mixed with different sorts of autos within the fleet, 40% will likely be electrical.

U-M researchers seemed on the unique plan of 10% EVs, evaluating it to an all-electric fleet. They discovered that greenhouse gasoline emissions beneath the ten%-EV state of affairs could be 15% greater than estimated by the USPS, whereas emissions from an all-electric fleet could be 8% decrease than the USPS estimate.

The U-M research additionally factored in estimated reductions in electrical energy grid emissions over the focused 20-year lifespan of the brand new mail vehicles. The USPS research appeared to imagine the grid will not get any cleaner than the current—however in fact it nearly actually will.

That makes a giant distinction. With grid decarbonization estimates factored in, U-M researchers predict that an all-electric fleet would lead to as much as 63% decrease greenhouse gasoline emissions than the company estimated, over the lifetime of the fleet.

These findings recommend the USPS ought to be electrifying at a price a lot greater than even the raised 40% threshold, Greg Keoleian, senior writer of the research, stated within the launch. The Inflation Discount Act, which leads to an in depth revamp of the EV tax credit score and, for a time, a restricted variety of eligible EVs, included one other $3 billion towards USPS electrical autos—so the second for a larger dedication is now.
